There are growing calls for the Royal Navy to be involved in preventing migrants from trying to cross the English Channel.
The Home Secretary, Sajid Javid, has declared it a "major incident" and is hoping for urgent talks with his French counterpart.
Immigration Minister, Caroline Nokes, has met with Border Force officers in Dover after around 100 people were caught making the dangerous journey since Monday.
One MP warned that the crisis could escalate into a "catastrophe" if the Navy were not called in.
Independent MP and Commons Home Affairs Committee member John Woodcock told The Sun: "The public is losing confidence in the struggling Border Force. It's time to stop the rot by sending in the Royal Navy.
"If the civilian force can't cope, the Navy must stop this crisis becoming a catastrophe."
Sajid Javid has appointed a "gold commander" to oversee the situation and give daily updates. He has also asked the Border Force to provide information on whether more vessels will act as a deterrent or encourage more people to make the crossing.
On Friday, Border Force officials brought the 12 men to shore at Dover and handed them over to immigration officials to be interviewed.
Another committee member, Tory Tim Loughton told The Sun: "There is a serious security implication, as this is a likely route undesirables who have been fighting in Syria will use if they want to return to the UK.
"Of course there is now a case for the Royal Navy to be brought in to do border protection in the Channel."
Since Christmas day over 50 migrants have tried to cross the sea and enter the UK.
